I recently purchased the larger 30" bag for an overseas trip, but it was so big that weight became an issue when packed full. The size also made it ungainly. I returned it for the 26".

The 26" bag fits the right amount of clothes and gear in a tight, stable package. Spinner wheels, two-stage handle, and bottom handle (between the wheels) make moving for good handling and loading/unloading. Internal features are simple - strap, lined pockets, and a shoe bag. Great bag I'm sure I'll use for years.
